Question

I want to write a long script for inserting and updating mongodb data.

1. Is it possible to call external js file that contains the script?
2. Is it pos

Answer 1

Use Load function

load(filename)

You can directly call any .js file from the mongo shell, and mongo will execute the JavaScript.

Example : mongo localhost:27017/mydb myfile.js

This executes the myfile.js script in mongo shell connecting to mydb database with port 27017 in localhost.

For loading external js you can write

load("/data/db/scripts/myloadjs.js")

Suppose we have two js file myFileOne.js and myFileTwo.js

myFileOne.js

print('From file 1');
load('myFileTwo.js');     // Load other js file .

myFileTwo.js

print('From file 2');

MongoShell

>mongo myFileOne.js

Output

From file 1
From file 2
